Remote-Cutoff Pentode
The 5749 / 6BA6W tube is a premium miniature type used as
a rf amplifier in standard
broadcast and FM receivers, as well as in wide-band,
high-frequency applications. This type is similar in
performance to metal the type 6SG7. The low value of
grid-plate capacitance minimizes regenerative effects,
while the high transconductance makes possible high
signal-to-noise ratio. iT Requires a miniature 7-contact
socket and may be mounted in any position.
